The link labeled "Two-empire system" actually points to a page about the political meaning of "two empire system". And that page does not have a disambiguation paragraph.
How is the five-empire system different from the old five-kingdom system that was used before monera was divied up into archaebacteria and eubacteria? — Ilγαηερ (Tαlκ) 02:34, 6 October 2005 (UTC)
Anonymous, the page you linked to does not have a political meaning. It is about the biological meaning of "two-empire system". Charizardmewtwo (talk) 16:49, 4 August 2016 (UTC)
Should the Empire be listed as an equivalent term for Domain? I believe that the Empire was originally conceived as a top-level rank encompassing all living things (Empire Organisata) as distinct from non-living things (Empire Inorganisata), and is therefore superordinate to what are now called Domains.

The two-empire system . . . , with top-level groupings of Prokaryota . . . , Eukaryota and the more recently[clarification needed] discovered Archaea empires.[citation needed]
Prokaryota, Eukaryota and Archaea — that's three, not two.
The linked "Two-empire system" page claims on the contrary that the empires are "Acytota and Cytota". (The latter contains all three of the "two" empires mentioned in the quote. Compare with Gnostrat's remark above. There are related comments on the "Two-Empire System" discussion page; in particular Solo Owl's remarks might be helpful.)
None of the three systems currently include non-cellular life.[citation needed]
This contradicts the linked "Two-empire system" page (which, as mentioned above, has an Acytota empire). — Dan337 (talk) 15:03, 6 October 2010 (UTC)
Should these be merged? —Preceding unsigned comment added by 96.227.239.56 (talk) 22:22, 3 September 2008 (UTC)
No, they are totally different! —Preceding unsigned comment added by 72.66.104.247 (talk) 20:32, 19 October 2010 (UTC)
Merge The resultant article would be much better than the two are separately. Spidey104 17:51, 4 January 2011 (UTC)
Definitely do not merge. They are separate issues. (December, 2011) — Preceding unsigned comment added by 86.5.215.150 (talk) 15:41, 9 December 2011 (UTC)
Don't try to Merge - If the 3-domain article is merged, what about the 2-empire article, etc? It would look oddly unbalanced if one bullet-point expands into a detailed section while the others remain as mere bullets. Either we leave it as it is or we merge all of them - but that raises the problem that we'd have to merge domains, empires, kingdoms .... which won't work. Best we leave it. Suggest delete the merge/discuss tag. Chiswick Chap (talk) 19:12, 5 September 2011 (UTC)
Recommend not merging. Too much variability in taxonomic "rules/opinion" (sadly). Quite confusing to have it all in one article. Easier to simply search for "Biology 3 domains" and get exactly what you're being taught. Agree with above. — Preceding unsigned comment added by 67.193.131.215 (talk) 22:15, 17 October 2011 (UTC)
What is a domain? (In a few sentences somebody-please!)--DJackD (talk) 08:39, 22 February 2009 (UTC)
A domain is a level of taxonomy higher than a kingdom.
Whay there is no page for Protein domains —Preceding unsigned comment added by 68.48.246.136 (talk) 02:14, 22 March 2010 (UTC)
In the last sentence, it says a citation is needed for the phrase stating that non-life is not currently grouped with domains. I don't think it needs a citation, for it is obvious, in my opinion. Heritagefarm (talk) 20:38, 16 November 2010 (UTC)
I forgot my notes in my classroom!! Can someone please tell me which Domain is the multi-cellular one. You know, the one all the animals and plants go under. Someone is bound to know something!!! — Preceding unsigned comment added by 99.20.86.79 (talk) 23:14, 21 March 2012 (UTC)
According to a recent study [1][2] giant viruses may represent a fourth "supergroup" of life, along side archaea, bacteria, and eukarya. Should this be added? -- 76.65.131.248 (talk) 13:27, 17 September 2012 (UTC)

hey, there is a frog on the picture, but there is also a tree under it. that's also eukarya :D what's more the animal is actually called tree frog! wouldn't it be better to show just a tree or just a frog, or mentioning each? — Preceding unsigned comment added by 193.224.72.252 (talk) 11:46, 20 March 2014 (UTC)
The image provided is not static, but rather is dynamically linked to the full set of sub-topics that are represented within the image. This seems counter to all other images represented in Wikipedia, in which clicking on an image provides a zoomed version to the image. A separate article or sub-article should provide all of the sub-topic links, rather than within this thumbnail sized image. SquashEngineer (talk) 13:29, 24 October 2016 (UTC)
I commented out an ostensible error at the end of a paragraph in the introduction:
and replaced it with
or more legibly
I am not a histologist, so there easily could be an exotic exception that I don't know about. The original writer, for example, may have been thinking of a nucleoid and was perhaps confused by the similar name. However, the standard line given in the linked article (cell nucleus) and prokaryote & eukaryote articles, is that prokaryotes have no nucleus at all. This postulate / definition is so thoroughly embedded in the articles I consulted, that the remarkable discovery of exceptions (which I, personally, would suspect are actually unusual eukaryotes that have drastically reduced or discarded their earlier nuclear membrane) there needs to be a citation to safeguard / validate the extrordinary claim. Lacking that, I'm going to suppose that it's an outright error. 107.115.33.14 (talk) 22:11, 25 September 2022 (UTC)
